Hi folks,
First time poster here. I’ve been using Fedora successfully for the past year and a half with no issues. Recently came across a bit of an odd one, I think Windows stomped on my EFI but I still consider myself a novice so hoping to get more eyes on this.
I have Windows 11 (insiders) and Fedora on the same machine but different disks, Fedora is installed on the same disk as the /boot/EFI. Recently when trying to boot any of the Fedora kernels from GRUB I will get: a flash, a reset of USB power (could be normal), then after a few seconds Windows boots up. Pressing ESC during the boot does not show any console logging, it seems to not be attempting to boot Fedora at all.
I thought it was GRUB at first so I followed the instructions here: GRUB 2 - Fedora Project Wiki to reinstall GRUB and then re-create the Grub configs. Unfortunately this didn’t work, and the issue persists.
I’ve made sure to update Fedora to latest using sudo dnf upgrade
and I’m on the latest kernel, though in my experience I’ve tried booting various known-working kernels and I have the same issue; hence my belief that a Windows update has done something strange.
My current workaround to boot into Fedora is to choose the Fedora 34 Rescue boot option, wait to watch this fail (Fail to mount boot.cfg), then reboot my machine, all of a sudden I can boot latest kernel no issue. However, every time I power off my machine I need to do this step again.
Lastly, when I hit ESC and Fedora is loading (on a successful boot) I see an error to load nvidia-powerd.service
, so I re-installed nvidia drivers from rpmfusion, however I still get it; and after looking it up I don’t think this is affecting my boot problems.
I’m unsure where to go from here, perhaps the MBR/EFI partition is corrupted or something, but I have no idea what to check. Thanks for any help
